An artificial island can be constructed at anywhere in any size & shape. It can be used for various purposes like industry, infrastructure, agriculture & tourism development.
In this report there is a short description about the construction process involved in artificial island like land reclamation, dredging, soil bed preparation, underwater concreting, advantages & disadvantages. An artificial or man-made island is an island or archipelago (group of islands) that has been constructed by people rather than formed by natural means. They are created by expanding existing islets, construction on exiting reefs, construction on sea bed, land reclamation or amalgamating several natural islets into a bigger island.

4. Artificial islands are being used to provide a platform for coal mine ventilation shaft access, positively contributes to the safety, effective ventilation and reserves of a coal mine.
5. Technology of artificial island construction is available to construct islands in water depths of 70 m.
6. Artificial islands become a focus for sea life, enhancing the marine environment.
